The coordinate of point B is at (29, -15): Option C is correct.
The formula for calculating the midpoint of two points is expressed as:
Given the coordinate points
A is (5, 7).
B is (x, y).
M is (17, -4)
Substituting into the formula to get x and y
17 = 5+x/2
5+x = 34
x = 34 - 5
x = 29
Get the value of y. Similarly;
-4 = 7+y/2
-8 = 7+y
y = -8-7
y = -15
Hence the coordinate of point B is at (29, -15)

Answer:
Area: 28 cm^2 Perimeter=20 cm
Step-by-step explanation:
A= 1/2 x b x h
A= 1/2 x 8 x 7
A= 28cm^2
P=a + b + c
P = 6+8+6
P = 20 cm
